I always use conditioner on my dog's long fur coat since he also has a thick undercoat as well. Conditioner keeps it smooth, less static prone, and helps keep his coat tangle free. This brand is cute, and seems to work ok but I don't particularly like the scent. I am kinda picky about that, so I wouldn't buy this one again. I tried other scents from this line too, and I didn't like any of them. Too bad, cuz it's definitely the cutest packaging!
